CHURN-PQWER.

SPECIFICATION forming part of Letters Patent No. 264,589, dated September 19, 1882,

Application filed uly 3, 1882. (No model.) I

1'0 all whom mag concern:

Be it known that 1, JOHN VVILBER, of Fall Brook, in the county of 'lioga and State of Pennsylvania, have invented a new and Improved Churn-Power, of which the followingis a full, clear, and exact description.

My .invention relates to improvements in that class of motive powers in which weights and springs are employed; and it consists in the peculiar construction'and arrangement of the parts, as hereinafter more fully set forth,

, and pointed out in the claim.

Reference is to be had to the accompanying drawing, forming part of this specification, which is a perspective view of my improved spring-power, in which a represents the-firstmotion shaft of a spring-power mechanism, of which I) is the spring, the ratchet-wheel, and d the pawl for holding the spring-in tension. e,f, g, and h represent the multiplying train of speed-gears; z, the balance-wheel; j, connecting-rod, and 7c walking-beam to work the churn-dasher shaft 1. The rod j is connected to one of the arms of the balance-wheel, so as to be shifted along said arm to alterthe length of the strokes of the dasher, as may be required for different quantities of cream.

From shaft a I have arranged a cord, in,'to the weight-drum 0, which is operated by the weight 17 and cord q, said cord passing from the axle of drum 0 up around an overhead roller, 1, in order to increase the range of the weight, said roller being mounted on the uprights a of a portable frame,'in which the machinery is arranged for convenience in shifting it about and setting itout of the way when not required for use.

represents a brake to' the balance-wheel, which is adjustable by the screw :10, or it may be a spring, or a spring and a screw together re-ent'orcing the power of the spring with the weight a machine of considerable capacity may be obtained, in which the power required to work the churn may be stored up with a few revolutions of the winding-up mechanism, so as to be accomplished in much less'time and also with less fatigue to the operator than by working the churn directly.

1 am aware that in churn-powers a combination of weights, wheels, pulleys, springs,

' connecting-rod j, and churn-dasher l, of the uprightsu, drum 0, roller t, cord m, passing around the shaft a, and drum o,'cord q,aml weightsp, all constructed, arranged, and operated substantially as described.
